provide an improved, simple and `efficient ma- 7.

chine for glazing bakers products. l A second importantV object-of theinvention is to provide a machine for the purpose whereby both the upperand the lower sides of an'article passing through the machine willbeeffectively 2" glazed.

A third important object of the invention is .to provide a machine for`the purpose whereby the glazing of both sides of an `article passingthrough the machine willk be effected simultaneously.

A fourth important object of the invention is to providev a machine ofthis class wherein liquid sugar is kept in circulation during operationof the machine. l Y

A fth important object of the invention is to provide `a novel machineloffthis class whereinV the circulating system for the liquid sugar andthe other parts contacted by liquid: sugar may be easily and effectivelycleaned so as to prevent clogging by crystallization of the liquid-sugarwhen the machine is not in operation.

With the above and other objects in view, as will presently be apparent,the invention consists in general of certain novel arrangements ofdetails and combinations ofparts hereinafter fully described,illustrated in the accompanying drawings and particularly claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and:

Figure 1 is a side elevation of a machine constructed in accordance withthis invention.

Figure 2 is a fragmentary section on the line 2 2 of Figure 1.

Figure 3 is a fragmentary section on the line 3--3 of Figure 1.

Figure 4 is fragmentary section on the line 4 4 of Figure 2.

Figure 5 is bottom view of a portion of a spray pipe suitable for use inthis invention.

Figure 6 is a section on the line 6 6 of Figure 5.

Figure 7 is a fragmentary elevation of portion of the invention, theview being taken from the side opposite Figure l and disclosing partshidden in that ligure.

Figure -`isa"fragmentary section on the line 8 8 of Figure '7p` i f Intheembodimentof` the invention as herein disclosed there is' provided apair of side frames of suitable structural material. Each of these sideframes Vconsists of a bottom member or sill l0 adapted to rest' on afloor or other support. Atthe ends of each sill are uprights ll whichhave their upperk ends connected by longitudinal members l2. -Anintermediate upright member l3connects each sill Il! with thecorresponding member l2 `offthe respective frame side. The two sideframes are suitably connected at the supplyor input end of the device bya cross member I4 and-at the output end by a similar cross member I5.-

Supported/between the side frames is a tank open-at the topa`nd havingsides AI 6. At the output endoffthe machinev the tank is shallower thanatI the input end and has a bottom which inclines downwardly from theoutput end toward theinputendasat il. From the input end of thisbottom-a vertical wall- I8 extends downwardly to the bottoni ofA-theinput end of the tank. This end ofthetank-fthus Jforms a collectingpit or sump for holdingfa` supply of the liquid sugar coating material.

Extending downwardly the bottom IB of the sump islapipe 20"which'connects with a horizontalpipe-zZlj-leading vtothe intake side of apump' 22." Extending from the outputside of this pump is a pipe having ahorizontal portion 23 and a vertical portion 24. The vertical portion 24is connected at its upper end to a spray pipe 25- extending horizontallyacross the machine from side to side thereof and supported in brackets26. The pump 22 is driven by a motor 21 and this motor also drives areduction gear 28 of any well known type. This reduction gear includes asprocket 29. At the output end of the machine there is provided a shaft30 which extends through the side walls of the tank and is journalled inbearings 3l carried by brackets 32 fixed to the outer faces of the tankside walls. On one end of the shaft 30 there is xed a sprocket 33 whichis connected by a sprocket chain 34 with the sprocket 29. On the shaft30 within the tank there is provided a pair of sprockets 35 each beingpositioned close to a respective side of said tank. The sprockets 35 arexed by set-screws 36 or other suitable means to the shaft 30.

At the input end of the machine the tank sides have oppositely disposedslots 31 extending horizontally and having their upper and lower edgessprockets 35 with the pair of sprockets 44, the

belt having adjacent its edges the usual holes' for receiving thesprocket teeth. It will nowy be plain that the crossheads and screwsconstitute belt tightener means. The belt 45 -lsfnea'rlas wide as thetank and the upperrunfofthis belt passes beneath the jet pipe 25`so thatarticles on the belt will receive the discharge fromj the jet holes 46.The belt 45 is made of any suitable porous material such` as wovenfabric. Beneath that portion of the belt below the jet1pipe 25 the upperrun passes ,over a plate 47 which is supported onfangle 'brackets 48securedl to theinner faces ofthe tanksides. The purpose ofthe plate 4lis to prevent-passage of the` glazing liquid for a certain distancealonggtheupperrun of the belt. At the input-end of the belt-there is afeeder tray whereonthe doughnutsyor Aother articles to be `glazed areplaced .for feeding onto the' belt 45. This tray is shown at 49. At theoutput end of-the machine thereis a rack 50 on which suitable trays orpans may b eplaced to-receive the glazed articles Afrom the belt.`

In order to be able to cl-ea-ngout .the pump and the pipes connectedthereto whenthe machine is shut clown a shut off valve is .provided .ineach pipe line close to the tankyand closeto the jet pipe, the latterbeing connected through a .union sothat the jet .pipe may bedisconnectedfor cleaning. In each pipe line there is -connecteda valve 52 forconnection andlcontrol, Aof -suitable wash out and discharge hoseqorpipes.. Also cleanout doors 53 are provided ,inthe `side w-alls I6 foraccess to the interior ofthe tank and the lower run of the lbelt, forcleaning when de sired.

In the operationA of the invention rvavlgluantity of liquid sugar orother coating material is placed in the sump oi the tank, thefvalves5|'.are opened and the motor 2l is started.. Theliquid sugar will bepumped from the sump and up to the jet pipe 25 to flow through the jetopenings 46 onto the upper run of the belt which is, at the time, movingslowly from left to right of Figure 1. The doughnuts are fed from thetray 49 onto the belt and in passing beneath the jet pipe are sprayedwith the glazing liquid. Since the pores of the belt are seal-ed beneaththe jet pipe there will be an accumulation of glazing liquid above theplate r4l and the underV sides of the articles on vthe belt will be wetwith the glazing liquid. After the upper run of the belt carries thedoughnuts beyond the plate 41 the excess of the glazingmaterial willpass down through the pores of the belt into the tank and will there owdown the*4 bottom\ Il to the sump for recirculation. The doughnutswillbe carried along and delivered at the output end onto trays supported onthe rack 50.

What is claimed, is: In a-glazing machine for bakery products, an opentop tank for containing glazing liquid, an endless woven fabric belttraversing the top of said tank, means for drawing liquid from said tankand delivering it onto successive lengths of said belt, saidmeansincluding a jet 'pipe extending vtransversely above said belthaving a multiplicity of jet holes on its under side and a pumphavingpipe connections with saidV tank and withsaid jet pipe, said belt havingupper and lower runs'.V and a plate beneath the upper run of said beltand` located beneath said` `iet pipe, the upper run of saidbelt movingover said plateresting on.` and in direct contact `therewith whereby thep'orosities of said'belt are `closed `in that portion of the belt incontact with 'said plate.
